Patent DE-4115220-A1 (DE)
Inventor: KAEPPELER KARLHEINZ
IPC: E06B7/086
Filed: 1991-05-10
Abstract: A blind is indicated which serves for the ventilation of buildings and which consists of a frame (1) with frame parts (8) which are parallel and lie opposite one another preferably in pairs and in which slats (4) are mounted. The pivoting movement of the slats (4) takes place via an adjustment mechanism (25) arranged between frame (1) and a crosspiece (20). In the arrangement, the pivoting of the blinds takes place downwards so that, with load applied, no lifting work has to be performed. As a result of this pivoting movement, it is also possible to forego a lateral frame-parallel seal and instead a stop seal (10) is provided. <IMAGE>

Patent DE-4120446-A1 (DE)
Inventor: WIESSNER FRANK DIPL ING
IPC: C07C29/38
Filed: 1991-06-20
Abstract: Formaldehyde and acetylene are usually converted into butynediol in the presence of a suspension catalyst in a cascade of reactors. The catalyst is separated from the product solution after the last reactor in the cascade and fed back into the first reactor. Here, depending on the degree of thickening of the suspension, a considerable proportion of the butynediol produced must also be fed into the first reactor of the cascade. This greatly hinders the conversion reaction into butynediol. Moreover, there is the risk of damage to the catalyst by a lack of acetylene, especially in the lines and the device for separating the catalyst from the product solution. According to the invention, the separation takes place in each individual reactor. This can be done by filters fitted in the reactor or suitable filter apparatuses outside the reactor. In the process of the invention, part of the catalyst in the reactors can be drawn off and replaced by regenerated and/or fresh catalyst. The catalyst drawn off from the reactors can advantageously be subjected to a regeneration. The exchange of the catalyst in the reactor may be intermittent or continuous. A quantity of catalyst of 50 - 200 g, preferably 75 - 125 g, is used in the reactors per litre of reaction solution.

Abstract: The invention relates to an apparatus, especially for medical purposes, comprising a support plate and piercing mandrils connected to the latter and arranged diametrically relative to one another, through which mandrils two flow channels are passed. The invention proposes that the apparatus have a shut-off element (5) interacting with one of the flow channels (21), which element releases flow through the flow channel (21) in an open position (Figure 2a) and blocks flow through the flow channel (21) in a locked position (Figure 2b), a liquid removal channel (12) of the apparatus (3) coming into flow connection with a section of the flow channel (21) which is open toward one piercing tip (19) in the locked position, and the liquid removal channel (12) opening into a connecting nozzle (25, 26). In the open position of the shut-off element the apparatus according to the invention permits transfer of liquid from a first container to a second container in which the piercing mandrils (19, 20) are inserted, whereas in the locked position of the shut-off element, with the piercing mandrils inserted, removal of liquid is possible through the connecting nozzle. <IMAGE>

Title: Delta modulation method for music signal transmission and recording - using representation of music signal by digital difference values between two scans
Inventor: KAMMHOLZ MARTIN
IPC: H03M3/02
Filed: 1991-12-20

Inventor: TURBAN KARL-ALBERT DIPL ING
IPC: H04J13/00
Filed: 1992-03-30
Abstract: Technical problem: In data transmission or transmission of redundancy-reduced signals, traffic flow and therefore required transmission capacity are not constant. State of the art: More or less intensive temporal utilisation of existing total capacity through the use of differing numbers of time slots in multiplex mode (TDMA, ATM) or through non-utilisation of residual time. Basic principle: Coded transmission and simultaneous use of differing numbers of codes which are orthogonal in relation to one another. Solution: Mixed CDMA-TDMA radio system. The number of channels (code division multiplex CDMA) assigned to an individual station is adjusted frame by frame on the basis of requirements in preceding frames.

Title: Inertia activated hazard flasher for vehicle - has different levels of activation, with automatic reset for strong braking.
Inventor: GRIEPENTROG JOACHIM ING GRAD
IPC: B60Q1/44
Filed: 1992-06-03
Abstract: The flasher control unit has an inertial mass displaced by braking and operating a mechanical switch to activate the hazard flashers when a set retardation is exceeded. The switch automatically resets when the retardation is reduced. If the retardation is above a second, higher level then the switch is locked into the operation position and can only be reset using a release switch (2). The second level includes impact and flip-over. The second, higher level is controlled by a second switch and a holding relay. Other switches monitor the position of the vehicle and activate the flashers if the vehicle flips over. The speedometer needle indicator can be automatically locked at its higher setting for subsequent accident analysis. The manual control of the flashers is not effected by any of the automatic modes. ADVANTAGE - Improved safety, indicates heavy braking as well as accident hazard.
